Fernando Torres

Price at time: £50m

Inflated price: £77,711,417

Revenue 23%

After starring for Liverpool Torres became a new record for a British transfer with his move to Stamford Bridge, winning the Champions League, Europa League and FA Cup, but never really hitting the same form that he did at Anfield.

Jimmy Floyd Hasselbaink

Price at time: £15m

Inflated time: £63,059,745

Ricardo Carvalho

One of the best defenders that Chelsea have had, a proper centre-back and made a fearsome partnership with John Terry under the managerial reign of Jose Mourinho.

Hernan Crespo

Price at time: £16.8m

Inflated time: £39,667,560

Revenue: 12%

Inflated time: £34,999,013

Revenue: 11%

Joining in 2012, Oscar had a lot of potential and a lot of skill, however he became something of a frustrating player at times for many Chelsea supporters.
